Indications of the travelling position are displayed on an atlas-gauge 5 by the lighting positions of LED of light emitting units 6, 7, and the reception-state of a satellite is indicated on the display 4 by winking lights. When the elapsed time is above three minutes, the display data on the display 4 are turned off to go out LED of the atlas- gauge 5, and the reception state of the satellite is displayed on the display 4 by lighting the lamps.

Title: Controller of motor for paper machine
Inventor: UMEMOTO FUJIO
IPC: G05D17/00
Filed: 1991-09-11
Abstract: PURPOSE:To prevent the paper cut by making small the torque ripple which occurs at the time of changeover of control on the side of a slave roll by the change from the separation state of the two rolls of a master roll and said slave roll to the pressurization state. CONSTITUTION:When a slave roll and a master roll 3 changes from the separation state to pressurization state, the speed controller 8 on the side of the slave roll 4 is changed over to the control based on the torque standard of the speed controller 7 on the side of the master roll 3. At the same time with it, the torque ripple at that time changes at a certain rate from the torque value in separation state to the torque value in pressurization state. Accordingly, the torque ripple arising at changeover of control can be made small. Hereby, the adverse effect such as paper cut, etc., can be prevented.

Filed: 1987-09-16
Abstract: PURPOSE:To form sharp images with high contrast by pouring the reverse charges of electrified charges to conductive toner which loses electrified charges owing to exposure and transferring them onto a blocking electrode. CONSTITUTION:The conductive toner 1 is uniformly stuck to the surface of a conductive drum substrate 5 by means of a hopper 2, and is fixed by a corona electrifier 3. When a writing head 4 exposes images, the toner 1 goes to a low resistance to lose electrified chargers. At that time, a conductive toner layer is brought into contact with the blocking electrode. A bias voltage 7 is impressed between the electrode 10 and the substrate 5, and charges of the reverse polarity of the electrified charges are exposed and poured into the low resistance conductive toner and transferred onto the surface of the electrode 10. The transferred toner is brought into contact with a transfer sheet, on which toner images are obtained by projecting the reverse charges of those poured from a transfer charger 12.

Title: Data transfer system
Inventor: SUZUKI TADAHISA
IPC: G06F13/00
Filed: 1988-09-19
Abstract: PURPOSE:To obtain a data transfer system being free from waste by returning simultaneously a fault signal, when a fault data channel returns forcibly a response signal in response to a data transfer request. CONSTITUTION:When a data transfer request is sent out of a controller 1, it is received by a request receiving response circuit 4, but since a fault detecting circuit 6 detects a fault, no start is applied to a data transfer control circuit 3. Accordingly, since communication of a transfer end does not come from the data transfer control circuit 3, the request receiving response circuit 4 does not return a response signal to the controller 1. However, in this case, an output fault detecting signal 18 of the fault detecting circuit 6 and a forced response signal 17 are both '1', therefore, an output of an AND gate 9 becomes '1', and the response signal is returned to the controller 1 through an OR gate 8, a tri-state gate 10 and a response signal line 16. Also, simultaneously with the response signal, a fault detecting signal 18 is sent out the fault signal to the controller 1 through a tri-state gate 11 and a fault signal line 15. In such a way, an useless access comes not to be executed.
